    Venus Optics KX-800 reviews

    KX-800 Flexible Macro Twin Flash is rated 4.0 out of 5 by 14.
    Rated 3 out of 5 by from Arm segment broke after about 6 uses In general I have loved this flash even though I didn't use it but a few times in the 1st year. While on a photo shoot in Costa Rica one of the bell shaped segments on one of the arms broke, right up the seam line. Of course, I was just 2 months out of my 1 yr warranty. Contacted the company and found out the only service is in Hong Kong. When I took it to UPS the price was going to be $210.00 to get it to the repair service. I had already taped it with gaffers tape in Costa Rica so I could keep shooting so I just purchased some 2 black gaffers tape and will just keep taping if I have any other mishaps. Beware if you need service

    Rated 4 out of 5 by from So far, so good So far, I'm loving this for the price. The only real problem I have with it is in finding a way to diffuse it. Not really their problem, but I think I'm going to have to find some creative means of diffusion that leqves me the use of both arms and keeps them movable. Still, its lighter than most speedlights, way more flexible, and output is just fine for close-up macro work.

    Rated 5 out of 5 by from Great for My Use I primarily wanted this flash for outdoor night hand-held macro moth photography. Many moths are highly reflective and both the on-board flash and the OEM Panasonic flash were too harsh (even using many different diffusers). The Bolt-VM-160 gave even light but wasn't strong enough so I needed supplemental light. This has been the winner! I'm still learning, but 1/32 power @1/160 illuminates well, the arms and lamps adjust perfectly for even lighting and stay in place, and the LED focus lamp is very powerful. Like it well enough that I'll be using it for day macro shooting as well.

    Rated 1 out of 5 by from Regret not buying from B&H The flash provides nice macro performance not found in other flash packages, and without the need for extra flash brackets, which I used and will make handheld pretty bulky. It does have longevity issues due to the nature of its design, using lock-line with several high stress point. The worse things is that I buy it directly from Venus Optics, with diffuser/arm bundle that never came with the package. They haven't response to my several email; maybe intentionally ignore me or arguing with their Hong Kong maker regarding who is responsible. GET IT FROM B&H ALWAYS!

    Rated 3 out of 5 by from so far works great until the batteries overheat this flash needs to be run from an external power pack to allow for quicker recycle time and there would be no overheating of batteries. i was shooting some beetles and flashes failed to fire or recycle fast enough for what i wanted...and batteries were hot when i took them out...had this issue before with other 4 aa battery flashes. if you don't shoot pictures rapidly its great.

    Rated 4 out of 5 by from Flash is good, but just didn't work out for me and my Sonys I'm giving this flash a four star rating, even though I decided to return it to B&H. It's a good product as other reviewers have stated; it works as expected and can yield good results if the user is willing to work with it. What follows is perhaps more pertinent to Sony A7xx or A6xxx series owners, but it may apply to other cameras as well.When I ordered the KX-800 macro flash unit, I knew that the macro flash would not be TTL and my Sony A7Rii and A7ii would have to be set to manual shooting mode. When the shutter is depressed, the KX-800 unit does flash, but other than that, the camera doesn't really recognize that a flash is attached. On the other hand, when I set my A7Rii on manual mode to 1/60s and f/16 and my Sony HVL-f43m on manual as well, the Camera and flash handshake when the flash is turned on and the Electronic View Finder and/or monitor responds by boosting the light signal so that you can see to focus, take a picture and then perhaps fiddle with the manual setting on camera and flash, take another picture, etc. to optimize exposure. When the sony flash is turned off, the monitor/EVF goes dark as you'd expect in manual shooting mode at this shutter speed and f stop in low light conditions.Using the KX-800, there is NEVER EVER a handshake with either my A7Rii, my A7ii OR my wife's A6000. The EVF and monitor remain dark no matter what. Other than triggering the flash unit, it's as if the Sonys don't even know it's there. The built in LED modeling lamp is bright, but not really very effective. When the KX-800 is employed in bright sunlight, using the above camera settings, the EVF and monitor are bright enough for focusing, but in the shade, high cloud cover or indoors in low light it's very difficult. This was a deal breaker for me. I much prefer ambient light for close up and macro work, but I wanted a macro flash for experimentation and those occasions when augmenting the available light is the only way to get a shot. Other folks may not mind or even enjoy a completely manual, stop-down focus, macro experience. I'm just too impatient and find it frustrating.Another quirk for Sony camera owners that I should point out is that, because of the painted/anodized msi hot shoe of the Sony A7ii, A7Rii and A6000, folks have resorted to scraping the finish off parts of their hot shoes to ground Canon, Nikon and generic flashes. Not willing to sand or scrape the finish off my cameras' hot shoes, I ordered a Neewer HC-511 Sony MSI to Canon Flash adapter There's one for Nikon, too, the HC-512; but it probably doesn't matter which one you use for the KX-800, because all you're doing is grounding the thing there's no TTL anyway. B&H doesn't sell this adapter so I ended up getting it at the place that begins with an @. The Venus Optics website also offers a Sony MSI to KX-800 adapter, but at twice the price and they probably all come from the same factory in China anyway.So I returned the KX-800 unit for store credit Thanks B&H and I'm thinking about going with a Kirk or Wimberly Macro Flash Bracket and an off-camera flash cable and use my dedicated Sony flashes with full TTL if I need it.

    Rated 5 out of 5 by from Works as advertised. The light output is actually stronger than I expected.� The top sync speed is 1/400 on my D500, faster than that, and part of the picture is blacked out. � The controls are easy to understand and use.� Power settings are from 1/1 to 1/128.

    Rated 5 out of 5 by from Opened up new photo opps for me I gave it 5 stars since it's working to my expectations. There's no TTL so all adjustments are manual which is fine. I've been using this for close up work such as water refraction shots. It works well. Previously I used large (regular) flashes. In addition, it's nice to be able to shoot Macro @ > 160/s for things like insect shots. Only concern I have is the durability of the flash arms but time will tell.
